RESUMEN
Schwannomas of the glossopharyngeal nerve are extremely rare tumors of the posterior fossa. In a 100-year review, a total of 42 cases were found between 1908-2008. The most common clinical data are associated with its location, the most common being cochlear vestibule symptoms and symptoms of glossopharyngeal nerve function. its diagnosis has now been facilitated by the use of magnetic resonance, however, it is very complicated to define preoperatively if the tumor originates from the ix, x or xi NC. We present the case of a 42-year-old patient with a syndrome of angulopentocerebellar syndrome, posterior torn (jugular) hole syndrome + anterior condyle (Collet-Sicard). The treatment used was surgical with transcondylar lateral extreme approach, with monitoring of cranial nerves and trans-operative evoked potentials.
